Abstract

The avian influenza viruses have been interacting for centuries with human and animal populations, thus being an important group for public health worldwide because of their capacity to perform genetic prearrangements that allow those viruses to pass from one species to another in environments related to mega cities, the increase of the agricultural frontiers and pressures on animal production systems. In February 2013 an epidemic of respiratory disease began in humans from Shanghai and Anhui, in China. After performing diagnosis tests it was determined that it was a genetic rearrangement of Influenza A (H7N9). The origin of this virus involves wild and domestic birds. Several studies have postulated that the most plausible place in which the transmission occurred could have been related to aquatic environments that facilitated the encounter between wild and domestic birds that are commercialized in city markets. Some aspects related to the origin of the disease and its dissemination are introduced, plus some questions about the behavior of the agent that are yet to be known as a consequence of the H7N9 emergency.
